Answer:
Molecular weight of the compound = 372.13 g/mol
Explanation:
Depression in freezing point is related with molality of the solution as:
Where,
= Depression in freezing point
= Molal depression constant
m = Molality
m = 0.26
Molality = 
Mass of solvent (toluene) = 15.0 g = 0.015 kg
Moles of compound = 0.015 × 0.26 = 0.00389 mol
Mass of the compound = 1.450 g
Molecular weight =

Explanation:
probably radiation. the sun's radiation waves are heating up the windows that are also heating up the house. but idek anymore sorry sister
Answer:
KI 1.0 M
Explanation:
Freezing point of a substance is a colligative property. This means that it depends on the amount of substance present is the system.
The freezing point is given by; T - Ta = K * m * i
Where;
T = freezing point of the pure solution
Ta = freezing point of the solution containing the solute
K = freezing point constant
m = molality of the solution
i= Van't Hoff factor
If we look at all the options provided, KI has only two particles in solution and a molality of 1.0 m hence it should exhibit the lowest freezing point of solution.
